Experience
2025 — Now
Principal Product Designer
Fidelity Investments · Dublin
Working as a web channel designer to improve user experience on the main fidelity.com website. Challenges include improving legacy navigation on website with heavy traffic and wide demograph of users, contributing to and implementing a new design system, providing standards and guidance to a large team of designers and wide range of dev teams, creating and testing re-useable patterns to embed consistency into the future.
2023 — 2025
Senior Product Designer
Fidelity Investments · Dublin
Building a new self-service experience that empowers plan admins to manage their ESPP (Employee Stock Purchase Plan) offerings from start to finish, significantly reducing dependence on Fidelity Operations. The solution offers global real-time data, actionable insights, and automation to make the entire process more efficient and streamlined.
As part of a small design team, we collaborate closely with multiple dev teams across different time zones to implement a lifecycle experience one block at a time. Planning, strategy, communication, and detailed prototypes played a key role in aligning such a large team on this ambitious project.
Additionally, I worked on a mobile-first enrollment initiative to simplify the process for hundreds of thousands of Fidelity users. This is a breakthrough for Fidelity, transitioning from a complex, desktop-only enrollment system to a more accessible mobile experience to allow users to accept employer-awarded stock.
2022 — 2023
Senior Design Specialist
Deloitte Digital / ACNE · Dublin
Designing a future state app for a large governmental body. I was the lead designer on this ambitious project working as part of a team of 20+ designers, analysts, developers & testers. We set about building an app to consolidate 100+ siloed apps using data and automation to improve workflow and processes along the way.
As part of this project we also began embedding accessibility into the state body through workshops and presentations leveraging WCAG principles. In tandem we built a design system that will shape the future of the body.
